[0002] The regulating valve is a regulating component in the fluid conveying system, which has the functions of shutoff, regulation, diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. The regulating valve can usually be used to control the flow of gas and liquid.

[0003] Liquids may carry solid impurities, which may cause valve blockage during transportation. Traditional valves can only adjust the flow rate and flow direction of the fluid, but do not have the function of removing impurities.

[0004] Based on this problem, a Chinese utility model patent with announcement number: CN209959996U discloses an adjustable valve. This technology can filter liquid materials and remove impurities, which is beneficial to keep the conveying pipeline unobstructed and prevent pipeline blockage. There is no need to set filtering equipment on the conveying pipeline, which simplifies the structure of the conveying pipeline and reduces equipment costs. However, in actual use, it is found that although the filter plate can filter some impurities, it cannot adjust the filtration accuracy of the fluid according to different usage requirements. Therefore, this valve needs to be improved. Utility Model Content

[0042] valve

[0043] The basic function of the valve in this embodiment is the gate valve in the prior art. The gate valve is a valve with a gate plate as the opening and closing part, and its movement direction is perpendicular to the direction of the fluid. The main function of the gate valve is to fully open or fully close. The working principle of the gate valve is simple and clear. The valve stem drives the gate plate to move up and down linearly through the driving device, thereby realizing the opening and closing of the fluid channel. When the gate plate rises above the valve seat, the valve is in a fully open state, and the fluid can pass freely; when the gate plate descends to fit tightly with the valve seat, the valve is closed to prevent the fluid from passing.

[0044] The adjustable valve of this embodiment

[0045] like Figure 1-Figure 5As shown, an adjustable valve of this embodiment comprises: a valve body 1, a fluid channel 101 is provided in the valve body 1, and a liquid inlet end and a liquid outlet end are respectively provided at both ends of the fluid channel 101, the liquid inlet end and the liquid outlet end are used to connect the valve of this embodiment with other pipelines, and an adjusting mechanism is provided between the liquid inlet end and the liquid outlet end;

[0046] The regulating mechanism includes a regulating box 2 and a driving structure;

[0047] The regulating box 2 is arranged on the valve body 1, and at least two filter plates with different apertures and a valve plate 303 are arranged in the regulating box 2;

[0048] The driving structure is used to drive the filter plate and the valve plate 303 to enter the fluid channel 101 and exit the fluid channel 101 respectively;

[0049] When the valve plate 303 enters the fluid channel 101, it is equivalent to the closing of the valve of a traditional gate valve, at which time the fluid in the fluid channel 101 is blocked from flowing. When the valve exits the fluid channel 101, it is equivalent to the opening of the valve of a traditional gate valve, at which time the fluid in the fluid channel 101 can pass freely. The filter plate enters the fluid channel 101 to filter the fluid in the fluid channel 101. By setting at least two filter plates with different pore sizes, these filter plates can enter the fluid channel 101 respectively, thereby achieving filtering of the fluid in the fluid channel 101 with different precisions. Specifically, the filter plate with a larger pore size filters the fluid with a lower precision, and the filter plate with a smaller pore size filters the fluid with a higher precision. The fluid filtering process is carried out when the valve is open.

[0050] Drive structure

[0051] like Figure 2 As shown, the driving structure includes: a sliding slot 201, a driving plate 401, a driving slot 202, a rack 402, and a gear 403.

[0052] The sliding groove 201 is vertically opened in the regulating box 2, the sliding groove 201 is connected with the fluid channel 101, and the number of the sliding grooves 201 is equal to the number of the filter plates plus the number of the valve plates 303;

[0053] The filter plate and the valve plate 303 are both provided with a driving plate 401, which is arranged on the upper part of the filter plate or the valve plate 303. A limiting shoulder is provided at the connection between the driving plate 401 and the filter plate or the valve plate 303, and the limiting shoulder is used to limit the movement position of the driving plate 401. The driving plate 401 is slidably connected with the sliding groove 201, according to Figure 2 In the middle position, the driving plate 401 is slidably connected with the sliding groove 201 in the vertical direction; the driving groove 202 is provided on the side wall of the sliding groove 201;

[0054] The rack 402 is arranged on the side wall of the driving plate 401 close to the driving groove 202 along the sliding direction of the driving plate 401; the gear 403 is rotatably arranged in the driving groove 202, and the gear 403 is meshed and connected with the rack 402;

[0055] Each filter plate or valve plate 303 corresponds to a gear 403 and a rack 402. The rotation of the gear 403 can drive the driving plate 401 to move through the meshing transmission of the rack 402, thereby driving the filter plate or valve plate 303 to move. Only by changing the rotation direction of the gear 403, the movement direction of the driving plate 401 can be changed, thereby enabling the filter plate or valve plate 303 to enter or exit the fluid channel 101.

[0056] Driving method of gear 403

[0057] The driving structure also includes a driving part, one end of which is connected to the gear 403, and the other end of which extends to the outside of the regulating box 2;

[0058] For details, please refer to Figure 3 A through hole 203 is provided on the outer wall of the regulating box 2, and the through hole 203 is connected to the driving slot 202. The driving part includes a rod-shaped body, one end of the rod-shaped body is coaxially connected to the gear 403, and the other end of the rod-shaped body passes through the through hole 203 and extends to the outside of the regulating box 2; the driving of the rod-shaped body can be realized by manual control or by electric control;

[0059] See also Figure 6 For manual control, a handwheel 5 can be set at one end of the rod-shaped body located outside the adjustment box 2, and the gear 403 can be driven to rotate by rotating the handwheel 5. This is also the most direct and simple driving method. In addition, a motor can also be used to drive the rod-shaped body to rotate, which requires the introduction of an electronic control system for control. The structure is relatively complex, but the control is relatively convenient.

[0060] Maintenance of drive structure and cleaning of filter plate

[0061] The top of the regulating box 2 is an open structure, and a detachable cover plate 6 is provided on the top of the regulating box 2. The cover plate 6 is detachably connected to the top of the regulating box 2 through fasteners and sealing strips, and the cover plate 6 can cover the sliding groove 201;

[0062] When the driving structure needs to be repaired, the cover plate 6 is removed, and the driving plate 401 and the filter plate or the valve plate 303 can be removed for repair, and the filter plate can also be cleaned at this time.

[0063] Filter method

[0064] The aforementioned filter plates are spaced apart along the flow direction of the fluid, and the filter plates can be used for filtering individually or in combination;

[0065] See also Figure 2 Taking two filter plates as an example, the two filter plates are named the first filter plate 301 and the second respectively, wherein the aperture of the first filter plate 301 is smaller than the aperture of the second filter plate 302, that is, the first filter plate 301 has a higher filtering accuracy than the second filter plate 302, and can filter smaller impurities in the fluid; in daily life, taking the fluid as water as an example, if you need to boil water or need cleaner water, you can choose the first filter plate 301 with a large filtering accuracy. If you do not require high water cleanliness for watering flowers or flushing, you can choose the second filter plate 302 with a smaller filtering accuracy.

[0066] Figure 2 In the embodiment, the first filter plate 301 is located in the fluid channel 101, and the valve plate 303 exits the fluid channel 101. At this time, the fluid in the fluid channel 101 is filtered by the first filter plate 301 and then discharged from the liquid outlet of the valve;

[0067] Figure 7 In the embodiment, the first filter plate 301 and the second filter plate 302 are both located in the fluid channel 101, and the valve plate 303 exits the fluid channel 101. At this time, the fluid in the fluid channel 101 is filtered by the second filter plate 302 and the first filter plate 301 in sequence, so that impurities with larger particles are filtered by the second filter plate 302, and impurities with smaller particles are filtered by the first filter plate 301. Such targeted filtration can prevent large particles of impurities from clogging the holes on the first filter plate 301, thereby reducing the frequency of cleaning the filter plates.

[0068] Figure 8 In the embodiment, the valve plate 303 enters the fluid channel 101 , and the valve is closed to prevent the fluid in the fluid channel 101 from flowing.

[0069] Although the figure does not show the schematic diagram of the second filter plate 302 filtering alone, it is not difficult for a person skilled in the art to understand the second filter plate 302 filtering alone. Figure 2 The filter mode of the valve can be switched by the display; the filter mode is usually switched when the valve is closed.

[0070] In addition, an appropriate number of filter plates can be set according to actual usage requirements to be applied in different scenarios.

[0071] The embodiments of the utility model are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
